After WD acquired SanDisk, it immediately launched its own brand of SSD solid state drive products and continued the naming method of previous hard drive products. First, it launched two series of solid state drives with GREEN green label and BLUE blue label, and they will also be launched for different device needs. SATA and M.2 interface versions, and both provide a three-year warranty. Among them, GREEN is a series of products that focus on entry-level and low-cost products, while the other BLUE blue label series has a slightly better performance and a maximum capacity specification of 1TB.

●WD 1TB blue label solid state hard drive out of the box and specification introduction

The blue label series SSD solid state drive launched by WD will have two interface versions, SATA 6Gb/s and M.2. It is mainly characterized by large capacity and durability. The official write life data can reach 400TBW and provide three-year service life. Limited Warranty Service. The blue label series solid-state hard drive tested this time is the 1TB SATA 6Gb/s version with the highest capacity specification.

There are only the main body of the hard disk and the anti-collision packaging material in the package.

The blue label series solid-state drives are made of black painted metal boxes, and the outer shell will also be affixed with an obvious blue label sticker.

From the sticker on the back, you can see that the detailed model of this hard drive is WDS100T1B0A-00 H9H0 .

The SATA 6Gb/s 2.5-inch version of the Blue Label series is designed with a thickness of 7mm, and there are fixed screw holes on the other side.

SATA 6Gb/s transfer interface on the hard disk.

After disassembling the hard disk, you can see that there is a thermal conductive patch attached to the inside of the outer cover to enhance the heat dissipation effect of chips and particles.

The main AD5201BRMZ10 chips and particles of the 1TB version of the 2.5-inch blue-label hard disk circuit board are placed on the same side.

The control chip in the WD blue-label solid state drive is the 88SS1074 model launched by Marvell "> 88SS1074 model "> 88SS1074 model "> 88SS1074 model "> 88SS1074 model "> 88SS1074 model "> 88SS1074 chip, which can support 15/ 16nm -ic/" title="16nm model">16nm-ic/" title="16nm model">16nm-ic/" title="16nm model">16nm-ic/" title="16nm model">16nm-ic/" title= "16nm model">16nm MLC or TLC flash memory particles and AES256 hardware encryption technology, and has a 4-channel transmission design.

Next to the control chip are two DDR3 cache memory particles launched by Micron, the detailed model is D9RVX.

WD's 1TB 2.5-inch blue label hard drive is equipped with 8 15nm TLC flash memory particles from SanDisk, the model is 05478 -ic/" title="05478 model">05478-ic/" title="05478 model ">05478-ic/" title="Model 05478">05478-ic/" title="Model 05478">05478-ic/" title="Model 05478">05478-ic/" title="Model 05478"> 05478 128G.

From the CrystalDiskInfo software, we can see that the firmware version of this blue-label solid state drive is X41000WD.

● WD 240GB Green Label Solid State Hard Specifications Introduction

WD's other entry-oriented GREEN series solid-state drives will also launch SATA 6Gb/s and M.2 interface versions. The official write life can reach 80TBW, and it also provides a three-year warranty service. The green label series solid-state drive tested this time is the M.2 interface version with a capacity of 240GB, and its size specification is designed to be 2280.

The control chip on the WD GREEN series solid-state drives is the SM2258XT chip launched by Huirong Technology, which also adopts a 4-channel transmission design, and the maximum transmission speed can reach 540MB/s for reading and 450MB/s for writing.

A total of 4 15nm TLC flash memory particles launched by SanDisk are equipped on the 240GB GREEN series solid-state hard disk, and the detailed model is 05497 064G.

Through the CrystalDiskInfo software, you can see that the firmware version of this green-label solid-state drive is X3311000.

●Introduction to WD SSD Dashboard application software

WD also provides an application software called WD SSD Dashboard for these two solid-state drive products, which mainly allows users to easily check the capacity, temperature and service life of the hard drive, and also provides some tool settings for those who need it. can be used in combination.

The performance chart in the software allows users to check the recent read and write status of the hard disk.

The tools page provides options such as firmware update and safe formatting, and also provides SMART diagnostic tools, which are convenient for users to check the health status of the hard disk.

●Effectiveness test

After reading the specifications and application software of these two series, let's take a look at the performance of the hard disk! Below is the list of components used in this test, for your reference first.

◆Processor: Intel Core i7-6700K

◆Host Saka: Gigabyte Z170X-DESIGNARE

◆Main hard drive: PLEXTOR M6S 256GB solid state drive

◆Memory: G.Skill DDR4-2666 4GBx2

◆Power supply: Gigabyte ODIN 1200W

◆Operating system: Windows10 64 bit

After being actually connected to the computer and formatted, the free space of the WD 1TB blue-label solid-state drive is about 931GB, while the formatted free space of the 240GB WD green-label hard drive is about 223GB.

●AS SSD Benchmark software performance test

The WD 2.5-inch 1TB blue-label solid state drive has a read performance of 514.47MB/s and a write performance of 444.05MB/s in the sequential read and write performance items.

●TxBENCH software performance test

The test results of the WD 2.5-inch 1TB blue-label solid state drive in the 128K sequential read and write project are 556.183MB/s and 512.696, and the test results of the 4K random read and write project are 41.449MB/s and 122.086MB/s.

The test results of the WD Green Label 240GB M.2 SSD in the 128K sequential read and write project are 558.329MB/s and 465.42MB/s, and the test results of the 4K random read and write project are 19.136MB/s and 115.811MB/s.

●Trial summary

From the hardware specifications and software function design, it can be concluded that the Blue Label series SSDs launched by WD this time are actually quite similar to the previous SanDisk X400 series, so they are similar in terms of performance and price, but the warranty part is from 5 years. It seems to be less competitive if it is shortened to 3 years, which is a pity.
